The bottle of hydrogen peroxide you used in Experiment 1: Ideal Gas Law - Finding Percent H2O2 is labeled as a 3% solution (the same as store-bought hydrogen peroxide). Do your experimental results support this (with consideration given to experimental error)

0.33%

Explanation:

So, from the question it is given that the mass of the hydrogen peroxide in percentage is = 3% that is to say there are 3.0grams of hydrogen peroxide in 100mL of water. Therefore, the number of moles of hydrogen peroxide = 3/ molar mass = 3/ 34.02 = 0.088 moles.

Also, the mass of hydrogen peroxide = number of moles × molar mass = 0.088 × 34.02 = 2.99grams. Hence, the percentage by mass = [2.99/100 mL 0f water] × 100 = 2.99%

Therefore, the error in percentage = [ (3 - 2.99)/3 ]% × 100 = 0.33%

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
